flashback arrestor/fire check?
I've appreciated so much all the info. I've gotten here! I'm constantly learning something new. And realizing how much I don't know. Today's question is in regard to a natural gas/O2 concentrator set-up. I've got a mini cc torch and an M-20 concentrator. After talking to the very helpful Jim at Carlisle, I've realized I need a fire check on the ng line. Do I need something similar going to the concentrator? And if so, should it be a fire check or flashback arrestor? Thanks,
